This is another simple project using a Wemos MIni and a couple of shields. This time we will connect a DHT11 shield and an SD card shield and we will log some temperature data from the dht11 to an sd card. The data will be saved as a csv file, this means you can quite […]

In this example we will connect a DHT11 sensor to our Wemos D1, we will then send the temperature and humidity values to thingspeak.

DHT11 digital temperature and humidity sensor is a composite Sensor contains a calibrated digital signal output of the temperature and humidity. Application of a dedicated digital modules collection technology and […]
